Try Metro Rubber (https://www.metrommp.com/
) for the rubber gaskets and window channel stuff. IF you can find true reproductions of the original MB stuff that would probably be better, but keep in mind at that time a lot of that kind of stuff was just bulk extruded rubber. Not like the molded stuff like they use today. So you might find something from Metro that is close that will work
Looks like the only engine available in the 170S was an ~ 1.8L I 4. (I thought that an I6 was and available engine in that chassis.) So, just how much room is available under the hood? What are the constraining dimensions? Uh, ok, looking at this cutaway view (http://allcarznews.com/data_images/m...nz-170--10.jpg
) sure is an "AH HA" moment and really shows the space constraint front to rear that you have to deal with. Wow, for such a long front end, that's pretty tight.
I've been planning to do my 69 GTX for over a decade now. The decision to use a Gen III hemi was kind of a recent move though. Believe me, thought about bailing more than a couple of times and just getting something newer that's really cool like an CLS63 AMG or an E63 AMG (drove one of those, wow). (Still planning on a CLS though at some time.) However a discussion with the guy that I'm going to have do the body/paint work got my enthusiasm up again. Looks like it's going to cost a lot less than I was planning on (it is REALLY hard to set aside $30,000 in cash for a paint job and body work). But a couple of things came to mind. First, the thought of working over/around $10,000 of fresh paint while doing a big mod like this is scary. Then I came across a deal on a complete 5.7L hemi (all accessories included) out of a car. That got me thinking that I'd change direction and get the car setup and running with the updated engine and drive train. And at least be able to drive/enjoy it until I'm ready for the next step. Also, that way if I drill/cut holes and then decide that I wanted it somewhere else the body guy can deal with my mistakes and fix them before paint. And then when it comes back from the body/paint work, all I'll have to do is put it back together. Anyway, I don't have the under hood space limitations that you have.
BUT, ANY progress is better than no progress, regardless of the direction you take on it.
So, lessee, you graduated high school in 09, you're like 24, eh? Hmmmm, lots of folks your age just aren't into the mechanical stuff I guess. Just tech stuff, huh? I've been alone my whole adult life. No family since I was 21. So I have to do everything all by myself. Get used to it. Don't let that stop you from chasing a dream or goal. Just be self sufficient. Besides, in reality, what difference is having someone else there going to make? Sure it's good to have help around, but unless you are handling big parts or doors, it really isn't going to matter.
